To all whom it may concern:

Be it known that I, FRANZ CECKA, a citizen of Germany, and residing atChemnitz, in the Kingdom of Saxony, Germany, have invented certain newand useful Improvements in Straight Hosiery-Frames, of whlch thefollowing is a specification.

My invention relates to improvements in straight hosiery frames, andmore particularly in hosiery frames, in which stop or retarding membersare provided for retarding the speed of the thread guides. A frame ofthis class is described in the patent of the United States toLieberknecht, Nr. 981,663, of January 17, 1911. As described in the saidpatent the object of the retarding or stop members is to soften theshocks or blows which are produced When the thread guide bars strike onthese stops. As shown in the said patent the speed of the thread guidesis retarded by gradually reducing the speed almost to zero, as thethread guide bar approaches the end of its stroke.

I have discovered, that for practical purposes it is suflicient toreduce the speed of the thread guide bars in a smaller degree, and moreparticularly to about one half the ordinary speed of the knittingoperation. Thereby I am enabled to provide more simple means forretarding the speed by connecting the retarding means with the knittingmechanism and constructing the same in such a way, that in knitting theslur is carried along each time in the direction of the knittingoperation, so that special mechanisms are avoided.

Therefore the object of the improvements is to provide retarding meansin a hosiery frame, which are very'simple in construction and effectivein operation. l Vith this object in view my invention consists inproviding retarding means, in which the degree of the retardationremains constant and is the same at the end of the movement of thethread guides as 'at the beginning of the retardation. In the practicalconstruction the retarding means consists of a stop member or brake forthe frame guide carrier, which is carried along in both knittingdirections and which moves at a lower speed than the slur or threadguide bar, and which is mounted in such a way, that it is overtaken bythe member which carries the in hosiery frames.

frame guide bars'along, and thereafter retards the same.

For the purpose of explaining the invention an example embodying thesame is shown in the accompanying drawing in a front view.

In the example illustrated in the drawings the hosiery frame is providedwith a slur connecting bar a; of usual construction, which is adapted tobe reciprocated from a knitting cam 17 through the intermediary of a rod0, a rocking knit-ting lever d and a connecting rod 6. On the bar a themember for carrying along the thread guide bar h provided with a threadguide 2' is mounted, which member consists of a bar fsecured to bracketsf mounted on the bar a. The bar 7 is frictionally engaged by an arm 9which is adapted to carry along the thread guide bar h. The saidcarrying mechanism depends upon the movement of the knitting mechanism,and the same speed is imparted thereto as to the knitting mechanism, andthe said speed is transmitted to the thread guide bar it.

The mechanism so far described is known In the example shown in thedrawing my improved retarding mechanism connected with the knittingmechanism consists of a rod Z, which is mounted for reciprocation inlongitudinal direction in suitable bearings m, and which is connected bya link at with a rocking lever d operated from a cam b by means of a rod0'. The member 9 which carries the thread guides along overtakes a stopmember s or 8 provided on the bar Z which always moves in the samedirection as the member 9 and at a smaller speed. When the member 9 hasthus overtaken one of the stops, it is forced to assume the smallerspeed of the bar Z, until it arrives at the end of the stroke of thethread guide which is limited by a fixed stop is. In order that thespeed of the member 9 can thus be retarded it engages the bar f byfriction, so that it slides longitudinally of the bar f. The sameoperation is performed in both knitting mechanisms, both retarding stops8 and 8 being alternately thrown into operation.
